Sony is about to start selling a memory card that's, apparently, been designed to help serve premium audio quality to listeners of digital music. It's literally a big lie, like those gold-plated HDMI leads, with Sony claiming buyers will hear "less electrical noise" when listening to music saved to it.

The 64GB SR-64HXA micro SDXC card costs around $160 (£105) -- five times the price of a standard model. Kerching. [WSJ]
